99-05-20  mattwe       Bugs 7593, 9256: On NT5, we now attempt to use the 
                       USERPROFILE and APPDATA environment variables for registry
                       icon paths.  When we do, the registry key gets a EXPAND_SZ
                       type.  Note that APPDATA is only available in NT5 starting
                       with build 2042.
